My Q2A site has been running fine for the last few weeks on the upgraded version. Then today, the whole site went down and the logs showed the following error repeatedly:

PHP Question2Answer MySQL query error 1030: Got error 28 from storage engine - Query: SHOW COLUMNS FROM qa_options

Then the site threw the following error and presumably crashed:

PHP Fatal error:  Allowed memory size of 268435456 bytes 
exhausted (tried to allocate 80 bytes) in 
qa-include/qa-db-install.php on line 487

 

Q2A version: 1.5 release
